This is Bath reports that subsurface imaging has added to a similar survey done in 1997. That survey revealed that the largest of the three circles was surrounded by a ditch with a wide entrance. The new survey, done with more modern equipment, discovered a second, smaller entrance. Archaeologists also found that one of the smaller stone circles stood on a leveled platform.
Stanton Drew’s main circle is more than 110 meters in diameter, making it the second largest stone circle in the UK, bigger than Stonehenge and second only to Avebury. The main entrance of its surrounding ditch faced a smaller stone circle to the northeast. Further away to the southwest was a third circle. Inside the main circle were nine concentric rings of wooden posts. These rings may have served as a sort of calendar marking important celestial events such as solstices and equinoxes. The megaliths of the three stone circles served a similar function.
Local folklore says the stones are a wedding party tricked by the Devil into celebrating on a Sunday. Stone circles have accumulated lots of folklore and several are said to be petrified people, including the Rollright Stones.
